Add create release github actions workflow

[Slowhand0309]

This pull request restructures the GitHub Actions workflows for building and releasing the project. The main change is splitting the macOS-specific build, sign, notarize, and artifact upload steps into a dedicated workflow, while simplifying the general release workflow for tagged pushes. This improves maintainability and clarity by separating platform-specific logic from the generic release process.

Workflow restructuring:

• Created a new workflow file create-release-with-artifact.yml to handle the macOS build, codesigning, notarization, and artifact upload steps, which were previously part of the main release workflow.
• Simplified the original create-release.yml workflow to only trigger on tagged pushes and create a draft release using the softprops/action-gh-release action, now running on Ubuntu instead of macOS.

Platform-specific build logic:

• Moved all macOS-specific steps (Xcode build, codesigning, notarization, stapling, and validation) into the new workflow, making the release process more modular and easier to manage.

Artifact handling:

• The new workflow now uploads the built and notarized macOS application as an artifact named QuickShelf-macOS.

Release creation:

• The main release workflow now focuses solely on creating draft releases with generated release notes for tagged commits, removing platform-specific build and signing logic.
